Definitely, it seems like anyone who was unrated got a huge rating boost compared to anyone who was rated.

I suspect it's because of the new rating distribution change, that might explain why only the unrated are affected.

    How is it possible??? Before the contest you are unrated i.e., 1500 and after solving 2 problems you become purple!!! That's very unfair for all who solved 5-6 problems and result in only few increment of their rating. :((

    I think there is some mistake and it'll be corrected soon. I did 5 questions in under 30 minutes and I got only a rating improvement of 53 (even less than predicted) and people solving 2 questions have become candidate-masters.. lol!

Mike forgot to set the starting rating to 0 and people are getting 2300 instead of 800 rating.

    nothing is wrong with your rating loss, you should know that you're rated based on how others perform, alot of pupils and newbies solved >= 5 and getting 4k+ rank in div3 won't cut it for a 1400+ guy

There is some issue. I got a warning saying that my solution coincides with some other solution. But the other solution is totally different with respect to mine one

    yes, it normal. almost everybody solved >5 problems, speed is the differentiator since you're rated based on others performances
